Innovative Stage6 R/T 70cc cylinder kit

Stage6 has a racing-focused division called Stage R/T and they have taken free rein to create this hyper-racing 70cc cylinder kit that not only delivers record-breaking performance, but also a beautiful design.

In terms of performance, this Stage6 R/T kit is absolutely top class for its size, and Stage6 has achieved close to 24 HP and can announce that the kit is also excellently efficient in terms of cooling, and this is partly due to the cylinder head that has cooling pockets for each mounting bolt, which effectively reduces the risk of hotspotting the bolts and piston.

On the surface, there’s nothing revolutionary about a 70cc cylinder kit with a 47.6mm bore, but what makes this Stage6 R/T kit special is the included CNC-milled adapter that is the mounting base for the cylinder, which eliminates the need for additional stud bolts, and because the Stage6Because Stage6 R/T has succeeded in designing the kit this way, they have been able to utilize more of the cylinder’s cargo for larger rinsing channels and exhaust port which lifts performance considerably compared to traditional kits in the same cubic class. The innovative mounting base is sealed with a Viton O-ring, and thanks to the clever design, Stage6 R/T has made it possible to service the piston without having to remove the mounting base. This makes life with this Stage6 R/T cylinder kit considerably easier.

Stage6 R/T 70ccm highlights:

• Innovative and beautiful design.
• Great power potential.
• Standard stroke length.
• Includes flange for mounting exhausts with 32mm flange.
• Uses spark plugs with long thread, e.g. BR9ES.
• May require milling of crankcase, instructions included.

Special features and power certificate

The special design and breathtaking performance unfortunately does not come without conditions. The Stage6 R/T 70cc cylinder kit can be installed directly on AM6 engines that are born with an aluminum cylinder from the factory. On newer AM6 engines born with cast iron cylinders, the crankcase must be milled slightly larger to make room for the cylinder, but don’t worry, Stage6 R/T includes a detailed manual to guide you through the process. On the other side of that, there is a solid power curve that Stage6 R/T has documented here, in the file the current setup is also shown.

Special dimensions of the Stage6 R/T cylinder to clarify whether the crankcase needs to be modified:

• Cylinder skirts, outer diameter: 56.7mm
• Cylinder skirts, length: 16mm
